Tou'ZZ whom it om concern:

Be it umvn that l, Vroron STANLEY subject of the King of Great reland,and residing at Nodis is, Julien lload, Northlields, ll aiing, London WEn land, have invented oerta: us

a specitiea on.

Th3 inventi relates to type casting mach es of the mind in which a pumpor ram forces the metal from a heated metal pot throu h a nozzle into amould which is neriodica brought into position against tne nozzleinorder that a type be cast and moved away therefrom, the matrix adaptedto ft an the face of the tvpe bein moved away from the l? of lfLil'Llthe mould parts being separated in order that the formed type may beseparated tang and ejected, and in which e mould is arranged on asliding carrierto which reciprocatory motion in a direction parallelwith the longitudinal. imparted to bring it into position against the naxle and to remove it therefrom, and n'ieans associated with the mouldl, ited by the motion thereof to and from the nozzle to effect thebringing together and the separation of tie two halves of the mould andin somecases the presentation to and withdrawal of the matrix from themould.

According to the invention, for effecting bringing together and theseparation of mould parts, a toggle is connected to a longation of themould block to which upper portion of the mould is secured to fixedpoint on the mould carrier, IlUQlilQ of the toggle being connected by"le means with a fixed point on the ng the two halves of the mould mustthe nozzle, an abutment I be pi vided against which the e of the mouldblock is brought '3 in that position.

av in such case. pron axis of the nozzle is ne against the other whenthe 7 ball mounted in the stud with the inclined surface to'se the twoportions of the mould together. he stud may, if desired, be associated wth a spring or othermeans, adapted to cause it to press resiliently uponthe mould block.

The "nould block is preferably secured to the mould carrier by meansadapted to permit i lEB'IHOUlCl block to he turned about its, lon udinalaxis and thus to facilitate the. inspection; cleaning, or othertreatment of i of the portion of the nould secured ereto. The abovereferred to prolongation of the'inould block may, for instance, be ofcircular crosssection and he rotatably and slidably mounted in a collarprovided with pivots engaging holes in a bracket on the mould carrierand be associated with the means, as for instance, a toggle, adapted toreel" the mould block about the aforesaid pirots to open and close themould, by a connection adapted topermitof rotational ll'lfi, ion of themould block about its longitudinal and also to permit longitudinalmotion ina direction parallel with said axis to permit of the positionofthe upper portion of the mould heingvaried relatively to the *lowerportion in accordance with the set-widthof the type to be cast.

Preferably, forejecting the tang from the break parts, means-operated bythe mo mould carrier is em- "ejector to' move against the actionrof the7 spring into its retracted position.v

The ejector may be a knife secured to a bar sliding in guides providedon the face f the moull carrier adjacent to the n sale on the melti pot;a helical spring may be arranged on the bar to draw the knife across theouter face of the parts of ll ei tt t 'l' l t e men 6 to ee lie ang,W11, a numoer adapted to co-operate with the cam to efiect theretraction of the knife is connected With or forms part of the bar.

Y s member conveniently formed by hencmg one end of tl e bar sharplydownsuch nner that the cam plate bent portion. v erto which the matrixse- "ahly slidably mounted in arrier and is, with advanced towardsnatrir; or for adjustsecuring the 71 .L ct between the race or and themould, orpreventing the prematurely or too forcibly o vhe mould.

For impar the clesii vi reciprocating motion to the "e'iould carriera-lever, to ell crank lever, operated i nay be employed.
